KNITTING MACHINERY Filed Dec. 29, 1944 IN V EN TOR. JACK FONTAINE whim ATTORNEYS Patented Apr. 18, 1950 UNITED STATES PATENT OFFICE KNITTING MACHINERY Jack Fonta'me, Cleveland Heights, Ohio Application December 29, 1944, Serial No. 570,270

1 Claim.

This application is a continuation, in part and as to common subject matter, of my application Ser. No. 568,960, filed December 20, 1944 and has reference more particularly to needle and sinker means arrangement, construction being provided which makes possible the manufacture of chain stitch products as well as ordinary stitch products, and in coarse or fine gage as desired. Other objects and advantages will appear from the following descriptions.

To the accomplishment of the foregoing an related ends, the invention, then, comprises the features hereinafter fully described, and particularly pointed out in the claim, the following description and the annexed drawing setting forth in detail certain illustrative embodiments of the invention, these being indicative however, of but a few of the various ways in which the principle of the invention may be employed. In said annexed drawing:

Fig. 1 is a side elevational view of an embodiment of the invention;

Figs. 2 to 4 are views of modifications; and

Fig. 5 is a perspective view of a modified detail of the structure of Fig. 4.

Referring to Fig. l, needles N in a gang or row suitably mounted for up and down reciprocation have arranged in relation therewith sinker S means in form of blades with two forward projections 2, 3, with a notch 4 therebetween, the blades being mounted by suitable means to oscillate between the needles, as by a rock shaft 5 and arm 6. The needles may be of any desired detail construction without or with a latch, as a yarn-actuated latch or mechanically operated latch. Rearwardly or forwardly of the needles and in inclined or sloping position is a plate 8 down which the knit web discharges. The upper end of the plate 8 may have recesses if desired, sufficient to permit the operation of sinker blades in close position. In operation, as the stitches are formed and cast off, the sinker blades push the web downwardly over the plate 8.

Similarly, in Fig. 2 there may be an inclined discharge plate 8a, and the gang of needles may have the sinker means S arranged on an incline or slant, the blades passing between the needles, and pulling the knit web downwardly in the direction of the reciprocation of the blades I over the plate 8a.

As another means of pushing or discharging the knit web from the needles, as shown in Fig. 3 the sinker means S may be in the form of discoidal members l2 mounted on a rock shaft I and having a peripheral projection 16 which thrusts against the knit work as the member I2 operates, and thereby the web is pushed on downwardly.

As shown in Fig. 4 the sinker S may be in the form of reciprocating blades l8 each having a forward projection l9 to engage the knitted work and push it on and downwardly, as the blades reciprocate. The blades may travel in a support or plate 20 having grooves 2| between the needles to receive the blades, and also having grooves 22 at the front for the needles. By such means, both the sinkers and the needles are adequately guided and guarded for high speed operation, and the web is discharged away from the needles downwardly. As a detail form of construction of the double grooved plate, if desired a plurality of channel members 24, Fig. 5, may be mounted in a gang or group, as in a lead or the like mounting 25, or suitable clamping means. With recesses or notches 2 l between the channel members above, there is thus again provided a double grooved guard for the needles and sinkers in the same arrangement as in Fig. 4.

In all of the forms, it is noticed that the knit web is discharged downwardly away from the needles, and bunching is prevented, even with complex and irregular designs. In the modifications shown in Figs. 1 and 2, the discharge furthermore is on an incline or diagonal slope downwardly, giving particular advantages in construction, and making possible chain-stitch fabrics as .well as products as of the so-called Raschel type of machine.

Other modes of applying the principle of the invention may be employed, change being made as regards the details described, provided the features stated in the following claim or the equivalent of such be employed.

I therefore particularly point out and distinctly claim as my invention:

In knitting machinery, a straight row of vertically reciprocable needles, a guard plate adjacent said needles along which the knitted work proceeds steeply down, a plurality of sinker blades thrusting the knitted work down along said plate, each blade having a notch clearing the plate and a forward projection to come to rest above the plate and another forward projection to come to rest below the upper portion of the plate, and a rock shaft adjacent to the needle mounting for oscillating said blades.

JACK FONTAINE.
